MAINTENANCE

Lamp

HIGH VOLTAGE

HIGH TEMPERATURE

HIGH PRESSURE

Contact your dealer before replacing the lamp. See the item “Optional Parts” in Table 12.

Before replacing the lamp, switch power OFF, remove the power cord from the power outlet, and wait approximately 45 minutes until the lamp has cooled. The lamp may explode if handled at high temperatures.

WARNING:

For disposal of used lamp, treat according to the instruction of community authorities.

Since the lamp is made of glass, do not apply shock to it and do not scratch it.

Also, do not use old lamp. This could also cause explosion of the lamp.

Premature lamp failure MAY be caused by an electronic component in the projector and not necessarily the lamp. If unsure contact your local service center.

If it is probable that the lamp has exploded (explosive sound is heard), disconnect the power plug from the power outlet and ask your dealer to replace lamp.

The lamp is covered by front glass, but, in rare cases, the reflector and the inside of the projector may be damaged by scattered broken pieces of glass. Broken pieces could cause injury when being handled.

Do not use the projector with the lamp cover removed.

Lamp Life

Projector lamps have a finite life. The image will become darker, and hues will become weaker, after a lamp has been used for a long period of time. Replace the lamp if the LAMP indicator is red, or the CHANGE THE LAMP message appears when the projector is switched ON. See Table 9 on p. 20 and Table 10 on p. 21.

NOTE: • The LAMP indicator is also red when the lamp unit reaches high temperature. Before replacing the lamp, switch power OFF, wait approximately 20 minutes, and switch power ON again. If the LAMP indicator is still red, replace the lamp.
